Thank you for your feedback!
You should have read the manual:
1. unregister your Nook.
2. Change e-mail address of B&N account
3. Register Nook again.
If you change the account e-mail address back to the old one, usually the Nook can connect again and you can change the e-mail address the correct way.
In your case I am not sure if this will work, because you tried to unregister the Nook. If this does not work, you will have call B&N.
